摘要
Abstract
In order to reduce the bit error rate and improve the transmission performance of the Visible Light Communication (VLC)system,the channel equalization technology is studied in this paper.The channel model of the indoor VLC system is established.The direct impulse response and reflected impulse response of the channel are also analyzed.A new variable-step-size Least Mean Square (LMS)algorithm is used to compensate the Inter-Symbol Interference (ISI)induced by multi-path effects.The experimental results show that the proposed LMS algorithm has faster convergence rate,which can achieve lower bit error rate when the system is stabilized.The adaptive equalizer has a better tracking performance on time-varying channel and system steady-state error is also reduced.关键词
